Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the affected wheel.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

A. Check Rotors

Measure the rotor thickness using a micrometer.
If warped (more than .002 inches off), replace the rotors.
If not warped, clean the rotor surface with brake cleaner and a lint-free cloth.

B. Replace Brake Pads

Remove the caliper by unscrewing the bolts holding it in place.
Slide off the caliper and hang it securely (do not let it dangle by the brake line).
Remove the old brake pads and inspect the caliper piston for proper movement.
Install new brake pads, ensuring they are properly seated.

4. Reassemble Components

Reattach the caliper and torque bolts to manufacturer specifications (usually around 25-35 ft-lbs).
Reinstall the wheel, hand-tighten the lug nuts, and lower the vehicle.
Torque the lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

5. Test Drive

Reconnect the battery.
Perform a test drive to ensure the issue is resolved and listen for any abnormal noises.
